Abstract

A concrete transit mixer can include a cabin having four doors for people to enter and exit the cabin, and a rotatable drum for mixing and pouring concrete. The mixer can include a water tank mounted below the cabin and a fuel tank mounted below the cabin. The mixer can include four distinct sets of steps to allow people to climb up to each of the four doors to enter the cabin.

Claims

1. A concrete transit mixer, comprising:

a front end portion, a rear end portion, and a longitudinal axis extending horizontally from the front end portion to the rear end portion;

an engine positioned at the front end portion along the longitudinal axis;

a cabin positioned behind the engine along the longitudinal axis, the cabin including a driver'"'"'s side, a passenger'"'"'s side, a first driver'"'"'s-side door, a second driver'"'"'s-side door behind the first driver'"'"'s-side door, a first passenger'"'"'s-side door, and a second passenger'"'"'s-side door behind the first passenger'"'"'s-side door and having a capacity to accommodate at least four occupants of average adult size;

a chassis;

a rotatable drum supported by the chassis at an inclined orientation and positioned behind the cabin along the longitudinal axis, the rotatable drum mounted on the chassis to rotate about an axis of rotation that extends from a front end of the rotatable drum to a rear end of the rotatable drum;

a water tank positioned below a rear portion of the driver'"'"'s side of the cabin; and

a fuel tank positioned below a front portion of the passenger'"'"'s side of the cabin;

wherein the cabin has a rear end, the water tank has a front end and a rear end, the front end of the water tank is aligned with a center of the second driver'"'"'s-side door along the longitudinal axis and the rear end of the water tank is rearward of the rear end of the cabin along the longitudinal axis.

2. The concrete transit mixer of claim 1, further comprising:

at least a first and a second seat positioned between the first driver'"'"'s-side door and the first passenger'"'"'s-side door; and

at least a third and a fourth seat positioned between the second driver'"'"'s-side door and the second passenger'"'"'s-side door.

3. The concrete transit mixer of claim 1, further comprising:

a first set of steps positioned below the first driver'"'"'s-side door;

a second set of steps distinct from the first set of steps positioned below the second driver'"'"'s-side door;

a third set of steps positioned below the first passenger'"'"'s-side door; and

a fourth set of steps distinct from the third set of steps positioned below the second passenger'"'"'s-side door.

4. The concrete transit mixer of claim 1, further comprising:

an access panel built in to a floor of the cabin that can be opened to allow an operator to access controls for operating the water tank.

5. The concrete transit mixer of claim 1, further comprising:

a first axle positioned under the engine;

a second axle positioned rearward of the first axle along the longitudinal axis;

a third axle positioned rearward of the second axle along the longitudinal axis; and

exactly one pusher axle positioned between the first axle and the second axle along the longitudinal axis.

6. The concrete transit mixer of claim 1, further comprising:

an access panel built in to a floor of the cabin that can be opened to allow an operator to access controls for operating the rotatable drum.
